Ratio of digestive tube length/standard length: 1.1. Feeds mainly on insects (Ref. 28681). When feeding, they use their barbels to search for prey on the bottom, although they don't turn over the substrate (Ref. 27701).

Occurs in littoral creeks, over sandy bottoms covered with dead leaves (Ref. 27188). Inhabits also lakes and rivers, but seems to prefer rivers with a very slight current (Ref. 6868). Prefers a muddy bottom covered with leaves and decaying wood, the latter providing for hiding places during the day (Ref. 35381). Feeds on fish and insects (Ref. 27188), benthic zooplankton and crustaceans (Ref. 35381). Omnivorous (Ref. 79585). Mainly nocturnal (Ref. 11225). Possesses poisonous spiny rays. Its sex ratio is 2:1 in favor of females. The male's reproductive apparatus includes multi-lobed testicles and accessory organs for secretion and storage. Fertilization is external. Non-sticking demersal eggs (1.1 to 2.8 mm diameter) are laid down, hatching after about 48 hours at 22°C. Ten days later, the larvae weigh approximately 100 mg but growth is slow (0.5 to 1.15 g per day).
